Andrew Carnegie：Autobiography of Andrew Carnegie, Additional Excerpt 354

The manufacture of steel was revolutionized by the Bessemer open-hearth and basic inventions. The machinery hitherto employed had become obsolete, and our firm, recognizing this, spent several millions at Homestead reconstructing and enlarging the works. The new machinery made about sixty per cent more steel than the old. Two hundred and eighteen tonnage men (that is, men who were paid by the ton of steel produced) were working under a three years' contract, part of the last year being with the new machinery. Thus their earnings had increased almost sixty per cent before the end of the contract.
